NOTES

1Temperature range T

MIN to TMAX: –40

°C to +85°C at 50 MHz and 140 MHz, 0°C to +70°C at 240 MHz and 330 MHz.

2Gain error = (Measured (FSC)/Ideal (FSC) –1)

× 100), where Ideal = V

REF/RSET

× K × (FFH) × 4 and K = 7.9896.

3Digital supply is measured with continuous clock with data input corresponding to a ramp pattern and with an input level at 0 V and V

DD.

4These max/min specifications are guaranteed by characterization in the 4.75 V to 5.25 V range.

Specifications subject to change without notice.
